feature, in types of local functions with free variables that are added as function arguments by lifting
add specifying type and attribute variables that occur in the types of these free variables/lifted arguments
so that the (partial) type of functions that use these variables and attributes can be specified
with syntax:

function_name :: E.^ type_and_attribute_variables : function_type

type_and_attributes_variables is a list of at least one of:

type_var *type_var .type_var (attribute_var:type_var) (attribute_var:)

these type and attribute variables are still polymorphic, but for recursive calls no new variables are created,
so polymorpic recursion is not supported for these variables

a local function type can still not be specified if:
an attribute inequality contains one attribute variable that occurs only in types of free variables/lifted arguments
(and the other attribute variable occurs only in the rest of the function type)
or a class constraint that contains both a type variable that occurs only in types of free variables/lifted arguments
and a type variable that occurs in the rest of the function type

foo :: a a -> Bool | eq{|*|} a

bug fix: combination of caching and omitted clasdefs

Universally quantified types used in class members
